Background

The magnetic pump (also called magnetic driving pump) is mainly composed of pump head, magnetic driver (magnetic cylinder), motor and base. The magnetic driver of the magnetic pump consists of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic separation sleeve. When the motor drives the outer magnetic rotor to rotate through the coupler, the magnetic field can penetrate through the air gap and the nonmagnetic substance isolation sleeve to drive the inner magnetic rotor connected with the impeller to synchronously rotate, so that the non-contact synchronous transmission of power is realized, and the dynamic sealing structure easy to leak is converted into a static sealing structure with zero leakage. For the rotor fittings in the magnetic pump, high-temperature steam is required to sterilize before the rotor fittings are put into use. However, the existing rotor fittings are generally plastic fully-coated rotors, and the swelling phenomenon can occur after the steam is introduced. Therefore, it is necessary to provide a further solution to the above problems.
